Greetings! I've used Excel for years, but this one caught me off guard. In
Excel 2000, I have the following data:

A B
1 3 1
2 1 10
3 2 100
4 5 1000
5 4 =B1+B2+B3

When I sort all five rows by column A, my formula gives me a #REF! error and
the formula is changed to "=#REF!+B1+B2". Doesn't Excel track the relative
changes of formulas during a sort? It seems to have tracked the 10 and the
100 in the table above but somehow lost track of where the 1 went.

This came to my attention when a formula returned an invalid value after a
sort -- even worse, I'd rather have an error than bad data!

Can anyone shed some light on this and is there a workaround? I tried
absolute references, but that didn't work.

Thanks in advance!
